Physics 100 Problems

Do these problems in two ways: both graphically and arithmetically.
This is a good time to notice that if you can do a problem two
different ways, especially two conceptually different ways, you
should do both. It's a way of checking, you deepen your understanding,
and you develop good habits of accuracy.

In problem 3.12, n is the relative index of
refraction, or, if the prism is in air and we say that
nair=1,
then n is the index of refraction of the prism.
If the geometry of 3.12 is too hard, don't agonize over it!
The phenomenon of minimum deviation is interesting and explains
some beautiful phenomena in the atmosphere -- the reason I
assigned it is mainly so that you would know about it.
